Product details
Overview
SPC5747GSK1MKU6R from NXP Semiconductors is an automotive-qualified Power Architecture® microcontroller featuring dual e200Z4 cores (160 MHz) and one e200Z2 core (80 MHz), 4 MB on-chip flash, 512 KB SRAM, end-to-end ECC, and ASIL-B-certifiable functional safety support for vehicle gateway applications. It integrates eight FlexCAN modules with optional CAN FD, four DSPI, six SPI, 18 LINFlexD, four I²C, Ethernet (RMII/MII + IEEE 1588), and hardware security module (HSMv2).
For engineers reviewing the SPC5747GSK1MKU6R datasheet, SPC5747GSK1MKU6R pinout, SPC5747GSK1MKU6R application, or SPC5747GSK1MKU6R equivalent, this page delivers verified technical context, validated pin mapping for the 176-pin LQFP-EP package, real-world automotive gateway use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SPC5747GSK1MKU6R implements a tri-core architecture: two high-performance e200Z4 CPUs (160 MHz, single-precision FPU, VLE encoding) and one e200Z2 CPU (80 MHz, VLE), all sharing memory coherency via E2 ECC-protected AHB interconnect. Its memory subsystem includes 4 MB flash (with RWW capability across 16 KB/32 KB data blocks) and 512 KB SRAM distributed across three ports with SMPU_0 (12-region) and SMPU_1 (12-region) protection.
Peripheral integration centers on automotive networking: eight FlexCAN controllers (all supporting CAN FD per family spec), 18 LINFlexD modules, dual Ethernet interfaces (ENET complex with AVB, IEEE 1588, multi-queue), and dual-channel FlexRay 2.1. Clocking uses FMPLL with FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz), while safety is enforced by FCCU, HSMv2, PASS/TDM, and ISO 26262 ASIL-B-certifiable subsystems.

Pinout & Package
SPC5747GSK1MKU6R is housed in a 176-pin LQFP-EP (exposed pad) package with 0.5 mm pitch, optimized for automotive thermal and EMI performance. Pin assignment follows NXP's standardized MPC574xG pinout layout for mechanical and signal compatibility within the family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_HV_A / VDD_HV_B / VDD_HV_C | High-voltage I/O supply inputs | Independent 3.3 V or 5 V supplies for I/O banks - enables mixed-voltage interface design |
| VDD_LV | Digital core supply input | 1.2–1.32 V core rail - requires external decoupling per Table 8 (Clp/ulp_reg = 0.8–1.4 µF) |
| FXOSC_IN / FXOSC_OUT | Main crystal oscillator interface | Supports 8–40 MHz external crystal - primary clock source for FMPLL and system timing |
| SXOSC_IN / SXOSC_OUT | 32 kHz real-time clock crystal interface | Enables RTC operation during low-power modes - critical for wake-up and time-stamped diagnostics |
| RESET_B | Active-low reset input | Asynchronous reset assertion - initiates boot sequence and clears internal state registers |
| BOOT_MODE[1:0] | Boot configuration pins | Selects boot source (flash, BAF via LIN/SCI, or debug) - determines initial execution path at power-on |
| ESR0 / ESR1 / ESR2 | External watchdog reset outputs | Drive external safety monitors - provides fail-safe reset signaling to companion ECUs or power stages |
Key Features
| Feature | Design Value |
|---|---|
| Tri-core deterministic execution | Two e200Z4 cores handle time-critical CAN/Ethernet stacks; e200Z2 manages diagnostics and LIN - eliminates software scheduling bottlenecks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GSK1MJU6R | 6 MB flash, 768 KB SRAM, 324-pin MAPBGA - adds 2 MB flash and 256 KB SRAM; larger package increases PCB area and thermal mass | Required for complex gateway stacks needing >4 MB firmware image + OTA staging partitions | Select when firmware size exceeds 3.5 MB or dual Ethernet + FlexRay + USB OTG/SPH must run concurrently |
| SPC5746GSK1MKU6R | 3 MB flash, 512 KB SRAM, no HSMv2 - reduced memory and missing hardware security accelerator | Suitable for cost-sensitive body electronics where cryptographic acceleration is not required | Choose only if ASIL-B certification is not mandated and OTA security relies on software-only crypto libraries |
Compared with MPC5748GSK1MJU6R and SPC5746GSK1MKU6R, the SPC5747GSK1MKU6R delivers optimal balance: sufficient 4 MB flash for certified gateway firmware, full HSMv2 security, and LQFP-EP packaging enabling easier automotive rework and thermal validation - making it the preferred choice for mid-tier vehicle platforms requiring ASIL-B compliance without BGA assembly complexity.

FAQ
What is the maximum operating frequency of each CPU core in the SPC5747GSK1MKU6R?
The SPC5747GSK1MKU6R features two e200Z4 cores rated at 160 MHz and one e200Z2 core rated at 80 MHz. These frequencies are guaranteed under automotive conditions (–40°C to +125°C ambient) with proper voltage regulation and cooling. The e200Z4 cores include single-precision floating-point units and variable-length encoding (VLE) for improved code density, while the e200Z2 core uses VLE for footprint reduction in auxiliary tasks. All cores operate synchronously from the same FMPLL-derived clock tree.
Does the SPC5747GSK1MKU6R support CAN FD, and how many CAN interfaces does it have?
Yes, the SPC5747GSK1MKU6R supports CAN FD on all eight integrated FlexCAN modules. This capability is confirmed in the MPC5748G family datasheet Table 1, which explicitly states "8 with optional CAN FD support" for the MPC5747G variant. Each FlexCAN module operates independently with programmable bit rates up to 5 Mbps in FD mode, enabling high-bandwidth diagnostics and software update transfers across vehicle networks without requiring external CAN FD transceivers.
What package type and pin count does the SPC5747GSK1MKU6R use?
The SPC5747GSK1MKU6R uses a 176-pin LQFP-EP (Low-Profile Quad Flat Package with Exposed Pad) package with 0.5 mm pitch. This is confirmed by the ordering code suffix "KU" in the part number and Table 1 of the MPC5748G datasheet, which lists "176 LQFP-EP" as the package option for MPC5747G. The exposed pad enhances thermal dissipation for automotive under-hood environments and provides a low-inductance ground path for noise-sensitive analog and high-speed digital circuits.
Is hardware security implemented in the SPC5747GSK1MKU6R, and what standards does it support?
Yes, the SPC5747GSK1MKU6R includes HSMv2 (Hardware Security Module version 2) and PASS/TDM (Password and Device Security) subsystems. It supports AES-128/256, SHA-256, and RSA-2048 cryptographic acceleration, secure key storage, and lifecycle-aware device censorship. These capabilities enable compliance with UNECE WP.29 R155/R156 cybersecurity management system (CSMS) requirements and facilitate secure boot, OTA firmware authentication, and secure debug access control - all verified in NXP's ASIL-B safety documentation for the MPC574xG family.
What is the flash memory configuration of the SPC5747GSK1MKU6R, and does it support Read-While-Write (RWW)?
The SPC5747GSK1MKU6R contains 4 MB of on-chip flash memory organized into 16 × 256 KB code blocks and additional data flash segments (including 16 KB, 32 KB, and 64 KB blocks). As shown in Tables 2 and 3 of the MPC5748G datasheet, the MPC5747G variant supports RWW (Read-While-Write) on designated flash blocks - enabling concurrent firmware execution and background programming. This allows safe OTA updates and dynamic parameter storage without halting real-time control tasks.
